The tool carrier 16, the parts'eearried thereby and the block 14 and sha ft 1l all foseillate on the bearing on the. trunnion screws 12. The cutting point is held in eutting Contact with the glass by means ot' a spring 28, connected at its lower end to the member 16 in rear of' the shaft 11, and at its upper end to an adjusting screw 29. The fnelnber 16 is preferably formed with a number of seats or engaging recesses 30, for the lower end of the spring, and whereby the tension of the spring may be adjusted to a. greater extent than is possible with the nut 29. The rear end of the member 1G has a finger lever 31, by means of which the cutting point can be raised out of Contact with the glass against the tension of the spring 28 in sliding the carriage idly upon the guide rods 8. Downward movement of the inember 16 to a sufficient extent to injure the tension of the lspring 28 is prevented by means ot a stirrup or stop 252. The downward movement of the cutting poi nt is limited by engagement with the stop projee tion 33 on the block 14 and the adjustable sto screw 34.

he numeral 35 designates a transverse shaft, one end of which irs secured in an arm 36, pivoted to one of the brackets 7. lts other end is secured in an arm 37, pivoted at 38 to the other bracket. 7, and extending downwardly to form a handle lever 39. AdiJ justably secured on the shaft 35 are a number of forwardly projecting gage arms fr0, which can be adjusted to any desired posi tion according to the wid th of the sheet or plate being cut. Each of these arms is provided on its lower side with a series ol stopor gage notches or projections Lll. The lever arm bzl carries tho piroted siirinopressed pawl lever 42, whose pin ov pawl 4? is adapted to enter in one ut a number of' perforatious 44, in the adjaoent brackets 7 (see Figs. and 7).

A.ff it is desired to out ofl a relatively narrow edge portion of the glass plate or sheet, the lever arm 39 is moved to the ri ght (looking at Fig. G) thereby depressing the gage arms 40 to a position in whirh thi.l first notch or projection 41 would art a stop for the forward edge ol the plate` or sheet. It the strip to be out oft' is wider, the shaft 35 is adjusted to bring one of' the other stops 37 in position to engage the front edge of the sheet. After the out has been rom pleted, the lever arm 39 is moved to the left a sufficient distance to raise the gages lil entirely above the horizontal plane ol the glass sheet, and thus permit it to he nloi'ed forward and off' from the euttirg table.

e Tlu operation will lle readily understood. The tages are properly adjusted by means of thf` lever 39 `nld fixed in the adjusted position. The sheet or plate to he cut is then moved forward until its forward edge Contacts with one of the gage stops 4l. The cutter carriage is slid idly over to the farther side of the table, und the utter rarriage is then released to causo thil spring 28 to Lrese the cutting `point into oontac't with the glass. The Carriage is then moved back across the table on theguidu rods fri and makes the cut.

In ease the carriage should he moved too far beyond the ridge of the sheet he fore starting-the out, the guard 2T helore described will. either prevent the ruttinf.,r point from dropping below the surface of the sheet or if the carriage is nmvod sutliV Ciently farso that the guard itself dropsover the odge ol the about, its beveled lower odge 2T will ride up our the edge of the sheet,

and thus raise the tool to rotting position.

The purpose of' this guard is to prevent the tool dropping down behind the edge of' the sheet where the rut is started, and thus` preventing its comingto rotting gironi-'ut i By means of lh#a several adjustniems de snrihrd, the cutting point ran lle not Haai-.lily lo the lorrect position for any imired :.rut, and can he rvadilg,- adjusted to different kinds of work. The gages also constitute au important feature of the invention, since the sheet or plate can he stopped at exactly the right position for any desired out, Without attention on the part of the operator, after the gages have once been set. The entire apparatus is 'very simple in its Construction, is :,ixceedingly convenient to operate, and enahlrs a large output of properly out plates or shorts to be produced` lo do not desire to limit ourselves to the jiartimilar construction .l 1d arrangement of the .i'arious parts which ive hare herein shown und deserilied it is obvious that these may he hanged in details in various ways within the spirit and scope of the appended claims.
